FOLDING CLAMP.

To all whom it may concern:

Beit known that I, LoUis J. Sowieso, a

citizenl 'ofy the United States, residing at ,lVIalta, in the county ofPhillips and State fof. Montana, have invented certain new and usefulImprovements in Folding Clamps;

I 4and I dohereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled inifthe f art to which it appertains to make and use Vthe saine.

My invention has for its object to pro- `vide an extremely simple andhighly eiiicient clamp intended for general use, but especially adaptedfor holding parts of a harness while stitching the same.

To the above end, generally stated, the invention consists ofthe noveldevices and combinations .of devices hereinafter described and definedin the claims.

, InI Ithe laccompanying drawings, which illustrate the invention, likecharacters indi- "oate like parts throughout the several views.

Referring to the drawings,

-Figure lis a view illustrating the im-v proved clanip in an operativeposition by means of 'full lines and in a folded position by means ofbroken lines; and

F ig. 2 is a side elevation of the improved clamp, as illustrated bymeans of full lines in Fig 1.

The numeral?, indicates a pair -of iiat basemembers connected by a hinge4r in a `manner to permit said members to be spread out 'fiat' end toend, or folded, one upon the other, as shown in Fig. 1. A pair of jawsliris connected, one to each of the base members 3 by hinges 6. Thesehinges 6 connect the jaws 5 to the base members 3, outward of theirinner ends, in a manner to permit said jaws to be set in convergingoperative positions, or folded outward into fiat engageinent with therespective base members, as shown in Fig. 1.

A thumb nut-equipped draw bolt 7 is 1nserted through a pair of alinedbores in the jaws 5, for drawingsaid jaws together, as shown in Fig. 1,or upon the work held therebetween. In this position of the jaws 5,washers 8 are preferably applied to the draw bolt 7 under the head andnut thereof. l'n the outer face of each jaw 5, is a shallow rectangularbox-holding recess 9 located outward of the bolt 7. The jaws 5 aresomewhat longer than the base members 3 and Specification of LettersPatent.

when folded thereupon, owing to their hinged relation thereto, bring thebox-holding recesses 9 outward of the outer ends of said base members. l1

Formed in each base member 3, outward of the respective hinge 6, is arectangular transverse opening 10.' These openings 10, when the basemembers 3 are folded, one upon the other, are alined to aiford areceptacle that is closed by the jaws v5, when folded onto said basemembers. Also formed in. each base member 3, outward of the respectiveopening 10, is a bore 11, that is alined with the bores in the jaws 3when said jaws are folded upon the base members, to receive the drawbolt 7, and thereby hold the clamp folded, as shown by dottedlines inFig. l. An open box 12 is placed between the jaws 5, when folded, withits bottom and upper edges seated within the recesses 9. Obviously, oneof the jaws 3 affords a cover for the box 12 and vthe other thereofhol'ds said box thereagainst, while the recesses 9 securely hold the boxagainst endwise or lateral movements, with respect to the jaws.

As previously stated, the improved folding clampis especially adaptedfor use in holding parts of a harness while stitching In this use of theclamp, the operatorfmay firmly and securely hold the clamp in aconvenient'position for his work by sitting upon a chair or bench withthe jaws of the clamp projecting upward between his legs and with theouter projecting end portions of the base members 3. The

receptacle 10-10 and box 12 may be used 'for rholding tools, rivets,etc.

What I claim is 1. A folding clamp comprising a pair of hinge-connectedbase members, a pair of cooperating jaws hinged, one to each' of thebase members, and means forsecuring the jaws in operative positions, thejaws when in operative positions being adapted to hold the base membersagainst folding movement.

2. A folding clamp comprising a pair of hinge-connected base membersadapted to be folded, one upon the other, a pair of c0- operating jawshinged, one to each of the base members and adapted to be folded ontothe respect-ive base members, and a draw bolt connecting the jaws, eachof said base members having a transverse opening, said openings.arranged to be brought into alineinent, when thebbase members arefolded one base members, and a draw bolt connecting the jaws andextending through alined bores foianedtherein, each of said base membershaving a bore that is alined with the bores 4in the jaws, when the clampis folded, to

receive the draw bolt for holding said clamp folded.. V j j '4. Afolding clamp comprising a pair of hinge-connected base members arrangedto be folded, one upon the other, a pair of cooperatingjaws hinged, oneto each of the base members and arranged to be folded thereupon, andmeans for securing the jaws yin operative positions.

` 5. A folding clamp comprising a pair of hingeiconnected base membersadapted to be' folded onev upon the other, a pair of cooperatingv jawshinged, one to each of the base members and adapted to be foldedY ontothe respective basemembers, and a draw bolt connecting the jaws andextending through alined bores formed therein, each of said base membershaving a transverse opening, said openings arranged to be brought intoalinement, when the base members are folded one upon the other, to a'brda receptacle that is closed tne jaws when folded onto the respectivebase members,

each of said base members having a bore that is alined with the bores inthe jaws when the clamp is folded to receive the draw bolt and therebyhold said clamp folded.2A

6. A folding clamp comprising a pair of hinge-connected base members,each having a transverse opening kand arranged to ,be folded, oneuponthe other, a pair; of` cooperating jaws hinged, one to veach ofthemembers and `arranged to vbe folded. upon the respective base members,said openings arranged to be brought 'into alinement when the basemembers are folded, one upon the other, to afford a reeeptaelethatis'closed by the jaws when folded onto the. respective base members andmeans for securing the jaws in either operative or foldedposition."

7. A folding clamp comprising apair'of hinge-connected base members, apair ofco-E operating jaws hinged, one to the intermediate portion ofeach of the base members, and means for securing the jaws; in

operative position. l j
